ACID RAIN
Introduction
Why are the trees dying? How come there are no fish in the lake? Why does
the paint on my Dad's car look so bad? Where does that terrible rotten egg smell
come from in our school yard every Spring? The answer to these questions is
simple; acid rain is responsible for many of the serious environmental problems
facing us today. While the answer may be simple, solving the acid rain problem
is not.
The Task
A local citizens' group has hired you, and a group of other researchers,
to investigate acid rain. You will take on the role of either a Chemist,
Ecologist, Health Scientist, or Economist and examine the issue from that
perspective. Working within this team, you will create a website detailing the
problems caused by acid rain and recommending ways that these problems can be
alleviated.
Within your group, decide who is going to assume the following roles. Use
the questions appearing under each role to assist you in your research. While
you are responsible for completing your section of the report, you will also be
responsible for drawing up a series of recommendations, along with the other
members of your team, on how to combat this serious issue.
CHEMIST
- What is acid rain?
- What chemicals make rain acidic, and how does it happen?
- Where do these chemical come from?
- How do we measure the acidity of rain?
- What is ph?
- Describe the ph range and list various things that correspond to the
various ph levels.
- What is the ph of normal rain, and at what level does the ph become
dangerous?
BIOLOGIST
- What effect does acid rain have on trees and soil?
- How does the effect of acid rain on trees and soild affect us?
- What happens when lakes and aquatic systems become acidic?
- How does acidic water systems affect us?
- Are the acquatic systems in our area being affected by acid rain? If
yes, to what extent?
- What are the danger signs of the effect of acid rain on aquatic
systems?
HEALTH SCIENTIST
- How does acid rain affect humans?
- What are some of the direct effects of acid rain on humans? Are there
any health problems associated with acid rain?
- What are some of the indirect effects of acid rain on humans? Does acid
rain affect our sources of food, water, and air.
- What are the consequences of the effects of acid rain on people?
ECONOMIST
- Does acid rain affect building materials?
- Does acid rain have an effect on architecture?
- What does acid rain do to our roads, highways, and bridges?
- What is the effect of acid rain on things made from metal such as
automobiles, trains, buses, and other means of transportation?
- What does the effect of acid rain cost us in terms of money?
- What are the economic consequences of acid rain on fisheries, forestry,
and agriculture?
While you are researching your particular area of concern, look for
solutions to the problems caused by acid rain. While the final section of your
report, the recommendations, will be drawn up by the entire group, you must be
prepared to offer solutions in your specific area of concern.
Web Resources
The Process and Learning Advice
The end product of this webquest will be the creation of a "web report"
detailing the causes and effects of acid rain. Each "scientist" will be
responsible for his/her section of the report while the recommendations and
conclusions will be arrived at through the cooperative efforts of the entire
group that you are working with.
- Get together with the other members of your group and decide who will
assume the responsiblities of each of the four roles. Do some "brainstorming"
on acid rain in order to come up with ideas for the focus of your "web
report". Develop a plan of action to determine the organization, contents, and
"look" of your web report. Know your main objectives and devise an outline of
all the information your site will contain
- Using the sites listed in the Resource section, begin to research your
project. Locate the information necessary to answer the questions listed under
your role in the Task section. As you will be creating a web report, find some
pictures that you can use to help illustrate the causes of acid rain and the
problems that it creates.
- Take notes as you do your research. Bookmark any sites that you find
useful so that you can refer to them again quickly if necessary. Keep in mind
the rules defining plagarism. Plagiarism occurs when you steal or use the
ideas or writings of another and present these writings or ideas as your own.
You are not allowed to borrow passages from books, or articles, or websites
without identifying them.
- After you have completed your research, begin writing the first draft
of your report. Make sure that you introduce your section so that the reader
knows what you are writing about. Remember that you are writing a report about
the problems caused by acid rain and not just a set of answers to a series of
questions. Be aware of the reader - just because you understand what you are
writing about doesn't mean that the reader does.
- Once each "scientist" has completed his/her section, meet with your
group and present your draft findings. This is the time that you can ask the
other members of your group for advice on revising your writing. Write your
final draft.
Decide, as a group, what is your position on acid rain. Determine the
recommendations and conclusions that your report will present. Determine which
members of the group will be reponsible for writing this section, and which
members of the group will put all the pieces of the report together.
Conclusion
After having researched and written your report on acid rain, you should
have a much clearer idea of the problems caused by this phenomenon. However,
being aware of the problem is not enough. Perhaps you may feel that we should be
doing more in solving this environmental issue. A good starting point would be
to write a letter expressing your concerns to your Member of Parliament in
Ottawa or your Member of the National Assembly in Quebec City.
